The 1.8 million gallons of sewage that overflowed from Aberdeen Proving Ground's Edgewood area into local waterways have since been diluted, the proving ground reported Wednesday.
Due to the approximately 5.6 inches of rain that fell in a 24-hour period, sewage bypassed the wastewater treatment plant at the Edgewood area on May 1, according to a statement from Aberdeen Proving Ground (APG).
Samples from King's Creek and the Bush River taken May 2 showed that the overflow was "diluted and mostly rainwater," APG said in a May 14 statement.
"In addition to the samples that were tested, observations of both waterways and areas of the bay to which the water flows [indicated] no adverse effects to wildlife were observed," according to the statement.
APG said that it applied lime to the impacted area and posted signage warning people not to fish, crab, harvest shellfish or swim there.
According to the statement, APG will continue to monitor the area in the event that additional treatment is necessary.
